The digital word is getting bigger hour by hour whereas the hardware associated with it is getting drastically smaller. Contrary to the popular belief, smaller the better is the way to go! Continue reading “Behind the Scenes with HDI PCB and its Applications”
Flying probe testing is a very important yet unexplored – or not enough explored – topic. It’s true that it might not be that easy to understand. But don’t let that intimidate you. If you are confident (or maybe not so confident) about your flying probe knowledge, just take the following quiz. Because even if you fail, no one’s watching. And if you pass, hurray you are a flying probe expert! Therefore, it is a win-win.
Drilling is the most expensive and time-consuming process in PCB manufacturing. The PCB drilling process must be carefully implemented since even a small error can lead to a great loss. The drilling process is considered the most critical and bottleneck of printed circuit board manufacturing. A PCB design engineer must always look into the board manufacturers’ capabilities before placing an order.
High-Density Interconnection or HDI substrates are multi-layer, high-density circuits with features including the fine line and well-defined space patterns. Increasing adoption of HDI substrates enhances the overall functionality of PCBs and limit the operational area. Continue reading “How to Avoid Crosstalk in HDI Substrate?”
International Traffic in Arms Regulations, or most commonly known as ITAR, is a set of government rules that control the import and export of Defence-related articles, services, and technology on the US Munitions List (USML). Quite heavy! Sounds more like something related to missiles and nuclear weapons but it has more to it. So, why am I talking about such a serious thing? What purpose does it serve in our PCB world? And most importantly, why should you be reading this?
Yes, It may Ruin Your PCB In-house Party.
Traces within the PCB are used to connect various components to various connectors. These traces can be identified as continuous paths of copper that exist on the surface of a circuit board. The trace width becomes crucial as it directly impacts on the working of the PCB. Additionally, increasing electricity flowing through PCB traces produces an immense amount of heat. Monitoring trace widths also helps minimize the heat build-up that typically occurs on boards. The conductor width also determines the resistance of the traces that directly affect the electricity flow.
